ROVING STOP-MOTION.

SPECIFICATION forming part of Letters Patent No. 589333, dated August31, 1897'. Application filed December 11, 1896. Serial No. 615,832. (Nomodel.)

To m/IZ whom it may concern:

Be it known that I, EPPA H. RYON, of lValtham, in the county ofMiddlesex and State of Massachusetts, have invented an Improvement inRoving Stop-Motions, of which the following description, in connectionwith the accompanying drawings, is a specification, like letters andfigures 011 the drawings representing like parts.

[O This invention has for'its object the production of a novel mechanismby which to stop a spinning-machine on the parting of thepartially-twisted rovin g or thread between the front roll and thespindle.

I The particular features in which my invention consists will behereinafter pointed out in the claims at the end of this specification.

Figure 1, in section, Shows a set of top'rolls with my improved rovingstop-motion added,

the dotted lines showing the stop-motion devices as having operated topart the roving. Fig. 2 shows the connecting-leg detached. Fig. 2 showsa modified form of leg and part of an intermediate lever in it. Fig. 3shows 2 5 a roving-guide detached. Fig. 4 shows the roving-guide carrierdetached. Fig. 5 shows one of the brackets for supporting one of theroving-guide carriers, it beingin practice attached to the usualreciprocating bar. Fig.

0 6 is a top or plan view of the intermediate lever, and Fig. 7 showsthe fulcrum-block for the said intermediate lever.

In the drawings, A represent-s part of a bar at one side of aspinning-machine, A a stand 3 5 supported thereby and having suitablebearings for the top rolls a b c and clearer-roll cl,

and e represents part of a reciprocating rovin -bar.

The parts so far described are and may be all of any usual constructioncommonly found in spinning-machines.

To the roving-bar, supported and recipro-' cated in any usual manner, Iattach by screws, as at 2, any suitable number of brackets f, 5 saidbrackets being bifurcated at one end, as

at f, to receive between its ends the rovingguide carrier g, they beingpivotally connected by a suitable pin g. One end of this carrier has alug 9 which receives one end 5c of a rod 9 on which may be adjustablymounted a ball or-weight 9 The carrier g'is shown as made as a doublebar, and between its open forked end (see the left of Fig.4) I place theupper end of aleg it, (see Fig. 2,) having a hole 3, which receives apin by which to pivotally connect the leg to the carrier. The broad footat the lower end of the leg it enters and rides in a slot hf of anintermediate lever h (shown as slotted atvits central part, as at hFig. 1) to embrace a pinor fulcrum h, supported in a stand h The saidpin 71 has applied to it a block m, having a slot on, in which is placedthe lever h the pin h entering the slot 77. of the lever and passing outthrough the holes of the block and entering the notch of the stand. Theblock m has a set-screw n, which may be turned in to act against theportion of the. lever above its slot to thus hold the lever firmly inadjusted position as to its length. The opposite or right-hand end ofthe lever 7L2 has a suitable pin or projection h, which passes under thethread-guide lever o, pivoted at 0 on a stand 0 said lever havingat itsouter end a thread guide o of usual construction.

The roving-guide carrier is provided at its right-hand end (see Figs. 1and 4) with a guide-groove 10, in which is fitted to slide the: shank 12of the roving-guide p, it having at its front side a projection 13,provided with a hole It for the passage ofthe roving on its way to therolls, the opposite side of the guide having a hook p.

The lower end of the guide 19 has a lug 15, provided with a hole whichreceives one end of a stop 1, shown as a rod or wire extended through ahole 16 in the bracket f, the lower end of the stop having a projectionto contact with the bracket f when the carrier 9 is lifted.

In practice the roving coming between the rolls a b c is passed over thebridge 17 of the carrier g, throughthe hole 14 of the rovingguide, andthence between the rolls and down 5 through the guide 0 to the traveleron the usual ring and thence to the spindle. In this condition, spinninggoing on regularly, the. lever 0 will be held down by the pressure onthe threadguide of the roving therein being ICO twisted to make thread,and said lever 0, acting on pin h, keeps the rear endof lever 7L pressedup against the leg 7L and holds the carrier g in its full-line position,leaving the roving free to be drawn through the hole 13 of the guide 1).Now should the roving being spun into thread break between the rolls andthe guide-eye, the lever 0, no longer held down, will rise and leave thepin or projection h, letting the weight g on the carrier turn the lever7L2, and at the same time the right-hand end of the carrier will rise,sliding on the guide 1), which will remain stationary, provided the saidguide is fitted loosely in the mouth at the end of said carrier, andafter the guide-carrier has ridden so far that the bridge 17 of thecarrier comes in contact with the roving under the hook p of the guidethe roving is slightly clamped, and as the carrier further rises ittakes with it the guide until the lower end of the stop-rod r meets thebracket f, when the roving becomes firmly clamped and is then partedbetween the projection 13 of the guide and the rolls a, and the end ofthe roving is left hanging down from the said projection. \Vhen theroving is to be mended in the usual manner, the lever 0 will be againturned down in its fullline position, the carrier 9 will be thereby putinto its full-line position, and in coming into said position the freeend of the roving hanging from the projection 13 and dropping on theunder roll (6 will be taken through be tween the rolls and into the eyeof the lever 0, and so on. As the roving-bar slides back and forth thefoot of the leg 7L slides back and forth in the notch of the lever 7L2.The leverage of the lever 7L2 may be changed by adjusting said lever inthe block on. The roving having been clamped, as described, and parted,the clamp continues to act and holds the roving with its free enddangling from the hole 1-1 in the projection 13, while the carrier 9 islowered into its normal working position, the descent of the carriercausing the (langling end of the roving to be deposited onto the underroll a and be caught and fed into the space between said rolls, and atabout this time the lower end of the guide 23 on the descent of thecarrier is arrested and the roving is unclamped.

Holding the broken roving clamped back of its free end and with its freeend held up above the rolls to be deposited thereon by the descent ofthe carrier into its normal position is an important feature of thisinvention.

If desired, the weight 9 may be omitted from the arm and a weight if, asshown by dotted lines, Fig. 1, be added to the lever 72?, and so, also,ifdesired, the leg 72, maybe moditied and in its place be used a leg 1(see Fig.

2,) having in it a horizontal slot i, into which enters one end of alever 1, equivalent to the lever 7L2, the said lever being straight atits end where it enters said slot 75 Having fully described myinvention, what I claim, and desire to secure by Letters Patent, is-

1. In a roving stop-motion, the roving-bar, an attached bracket providedwith a rovinggnide carrier, a roving-guide, and means to move saidcarrier and cause it on the breaking of the roving being spun, to claspthe roving between itself and said roving-guide to break the samebetween the roving-guide and the rolls, substantially as described.

2. A roving-guide, its attached stop-rod, and a guide for said stop'rod,combined with a roving-guide carrier made as a lever, the movement ofsaid lever in one direction causing the roving-guide to be moved with ituntil the stop-rod of the roving-guide is arrested, the further movementof the said carrier after arresting the movement of the rovingguideparting and holding the roving ready to be again delivered to the rolls,substantially as described.

3. The roving-guide carrier made as a lever provided with a guideway, aroving-guide in said guideway and provided with a stop to control itsupward movement with relation to said carrier, a leg connected with saidcarrier, and a lever provided with a thread-guide, combined with anintermediate lever, to operate, substantially as described.

4. The roving-guide carrier made as a lever provided with a gnideway, aroving-guide in said guideway provided with a stop to control its upwardmovement with said carrier, a leg connected with said carrier, and alever provided with a thread-guide, combined with an intermediate lever,and means to support it in an adjustable manner on its fulcrum,substantially as described.

5. The combination with a set of rolls, a carrier, and means to move itvertically, of a sliding roving-guide mounted in ways in said carrierand adapted in the upper position of the carrier to clamp and brace theroving, leaving a long dangling end, and to unelamp said roving as thecarrier comes into lowest operative position, the descent of the carrierpulling the dangling end of the roving between the rolls, substantiallyas described. In testimony whereof I have. signed my name to thisspecification in the presence of two subscribing witnesses.
